Data Standards Data Quality Assessments –Standardize the process through detailed analysis procedures –Identify the different data quality problems using standardized notation –Summarize the analysis in reports to communicate to others –Create detailed examples to coincide with the analysis procedures © 2011

15. Data Standards Data Standardization –Address Leverage address standardization software –Phone and Email Leverage data quality software to standardize –Business data Leverage valid values and master reference data to standardize data across the organization © 2011

16. Data Standards Data Security –Identify sensitive data –Clearly define and publish procedure for requesting access –Identify and maintain lists of users with access rights –Validate regularly that the user still needs access © 2011

17. Metadata Standards Documented agreements on representations, formats, and definitions of Metadata © 2011

23. Metadata Standards Data Requirements –Align with the business requirements –Each business requirement is likely to have matching data requirements –Clearly define the data content to be captured –Profile existing data sources © 2011

24. Metadata Standards Data Profiling –Identify standards for utilization Create a step-by-step process for preparing the data, profiling the data, and analyzing the results Identify and document the communication method to the business and IT © 2011

25. Metadata Standards Data Profiling –Column Profiling Identify both valid and invalid –Values –Patterns –Data types –Lengths Standardize notation –Descriptions –Problems © 2011

26. Metadata Standards Data Profiling –Table Profiling Validate key structure Identify candidate keys Identify natural keys Identify and document exceptions or violations –Cross-Table Profiling Identify redundant data Validate foreign keys Identify orphaned rows © 2011

27. Metadata Standards Data Profiling –Table Profiling Validate key structure Identify candidate keys Identify natural keys Identify and document exceptions or violations –Cross-Table Profiling Identify redundant data Validate foreign keys Identify orphaned rows © 2011

28. Metadata Standards Data Profiling –Cross-system Profiling Identify redundant data Identify inconsistent data Identify common matching criteria © 2011

29. Metadata Standards Data Quality –Consider requiring as part of all profiling initiatives –Capture and store in metadata repository –Establish thresholds –Trend monitoring © 2011

30. Metadata Standards Data Modeling –Enterprise Data Model Identify high level view of where the data lives across the enterprise Centralize to make accessible across the organization Consider identifying enterprise-level entities for important data © 2011

31. Metadata Standards Data Modeling –Model Standards Standardized development process Model naming convention Name standards Data type standards Clearly documented review process © 2011

32. Metadata Standards Data Modeling –Logical/Physical Models Standards Model or project narrative Subject area Entity Relationships Attribute Identifier Derived and BI Elements © 2011

33. Metadata Standards Data Modeling –Metadata Validation Column level –Values –Patterns –Data types –Lengths Table level –Key validation Cross-table level –Foreign key relationships © 2011

34. Metadata Standards Mapping –Standardize mapping process –Standardize format of mapping document –Require data profiling as part of the mapping process or to validate mapping © 2011

35. Recommendations Publish or centralize data and metadata standards Integrate data and metadata standards into the SDLC Include standards review during onboarding Identify and publish the list of stewards Enforce standards with offshore teams © 2011

36. Summary Data and metadata standards need to be developed and supported by both IT and the business Well defined standards will enhance the development of new applications and simplify the integration of data across the organization © 2011
